Every summer people get mad over the lack of female artists on music festival line-ups. This year, Reading, Leeds and Download were some of the events that came under fire for their nonexistent gender balance. But what about your average UK club night? 

Very Male Line-Ups is one Tumblr that wants to highlight the lack of females on the bill for clubs, gigs and festivals under the tagline "helping bromoters do better". 

So far, the focus has been on electronic music – nights like Secret Sundaze, Feel My Bicep and Fabriclive have all been singled out for having all-male line-ups. (The results are always helpfully accompanied by an image of Rihanna giving a thumbs up in disgust.) 

On Twitter, the people behind the website explain: "This blog highlights the lack of women on event line-ups. We recognise that so much more around visibility in music needs addressing. Issues around race, disability & trans visibility in our music scene need addressing. We express full solidarity for these."
